The mission would lay the groundwork for Elon Musk's goal to land humans on Mars.

Previously, Apollo 11 astronaut Buzz Aldrin told Tech Insider that we'll need at least 25 years and cooperation between three rival nations to make a crewed Mars mission happen.

Musk, the tech billionaire who founded SpaceX, had previously said he expected to do it in 11 or 12 years.

That sounds ambitious because it is.

On April 27, the SpaceX Twitter account teased the company's upcoming plans:

SpaceX confirmed the announcement by email with Tech Insider.

"These missions will help demonstrate the technologies needed to land large payloads propulsively on Mars," SpaceX confirmed. "Red Dragon missions to Mars will also help inform the overall Mars colonization architecture that SpaceX will reveal later this year."

An image from a SpaceX launch that was tweeted along with the new announcement.SpaceX/TwitterA recyclable rocket is just part of the equation, though. SpaceX is also developing a whole suite of spacecraft destined for the Red Planet.

For example, models of its Dragon space capsule — a vessel designed specifically for shuttling cargo and eventually astronauts to the International Space Station — have enjoyed a round of successful tests in the past few years.

But if Musk has his way, a more advanced model, called Red Dragon, will carry the first humans to Mars.

The SpaceX tweet implies this first Red Dragon launch will "inform overall Mars architecture," probably scouting and doing necessary groundwork before sending a later crewed mission.

We're not sure what Musk's full plans are, and we may have to wait until September 2016 to see them.

Until then, you can peruse a storm of Instagram posts that Musk published in September 2015. They highlight a few illustrations of Red Dragon and what it would look like landing on Mars.

After traveling millions of miles, the Red Dragon would finally enter Mars' orbit.

Then it would plunge into the Red Planet's atmosphere, traveling so fast that it will need to withstand temperatures of around 3,800 degrees Fahrenheit.

3/

Once it nears the surface of the planet, Red Dragon would fire its supersonic thrusters to line itself up for the landing.

The capsule would then touch down on Mars.

And the humans inside would step out onto Martian soil.

SpaceX has already successfully tested Dragon and Dragon 2. The Red Dragon could be on its way sooner than we think.

Musk is certainly optimistic. He thinks we'll see the first humans on Mars in 11 or 12 years.
